Hello: I'm hooking up a sidearm heater to an existing electric water heater for use with an outdoor wood furnace. I've seen diagrams showing the upper port of the potable water side hooked up to the anode port, the TPV port, and the cold water inlet port. My initial thought is that plumbing it into the cold water inlet with the appropriate check valve and expansion tank woukd be the best way to do it. My concern is that the dip tube on the inlet port runs to the bottom of the storage tank and I'm afraid this will affect the thermo siphon action. Anybody out there have any experience with this?
